Title: Improvements in tubulous vapour generating and vapour heating units
Inventor: SCHAAP WILLEM FREDERIK CAREL
IPC: F22G5/06
Filed: 1954-04-23
Abstract: 771,924. Combustion apparatus. BABCOCK & WILCOX, Ltd. April 21, 1955 [April 23, 1954], No. 11838/54. Class 51 (1). [Also in Group XIII] A water-tube boiler has a vertical furnace 1 lined with steam generating tubes and divided into two chambers by a tubulous partition, the furnace lining tubes and those of the partition extending between lower headers such as 12, 24, 34 and an upper steam and water drum 50. The lower part 1b of each furnace chamber is hopper shaped whilst near its upper end . an arch 21 projects from the furnace rear wall 20. Each chamber is fired by two vertical rows of pulverized fuel burners 14, combustion gases flowing past a radiant superheater 43 comprising pendent tubes 44, 45 lining the upper part of the furnace into a lateral pass 28 locating a secondary .superheater 53 comprising pendent tube platens widely spaced across the pass. The gases leaving pass 28 turn at 70 for downward flow through parallel passes 71, 72 lined with steam superheating tubes and which are provided with flow control dampers 140, 150 at the respective outlets. Pass 72 contains a reheater 120 comprising five spaced banks 312 of nested, sinuously bent tubes. Pass 71 contains a primary superheater 110 arranged in fivs spaced banks 212 as for the reheater. The gas streams from passes 71, 72 combine for flow through a further downpass 141 containing an economizer 142 and finally discharge through a lateral duct 163 to the boiler stack. From each side of the bottom of downpass 141 ducts 167 lead to gas recirculation fans 168 which withdraw cooled flue gas from the downpass. and supply it to each furnace chamber hopper bottom through duets 170, 174 or through ducts 171 to ports 42 located in the front wall 10 of the furnace at the level of the arch 21. The recirculated gas flow is controlled according to steam temperature by dampers in the respective supply ducts. The boiler is designed and the dampers 140, 150 set so that at full load the temperature of the reheated steam is at the desired value whilst that of the superheated steam leaving the secondary superheater is too high, the superheat temperature being lowered as necessary by an attemperator 49. With decreasing load, when the temperatures of reheat and superheat tend to fall, flue gas is recirculated first to ports 42 only to increase the amount of heat available for reheating, the supply of water to the attemperator being decreased. At low loads, below superheat attemperation range, flue gas is recycled to the bottom of each furnace chamber to reduce the amount of heat absorbed therein by the steam generating tubes.

IPC: F02M41/12
Filed: 1951-05-23
Abstract: 697,542. Fuel-injection pumps. C.A.V., Ltd. May 21, 1952 [May 23, 1951], No. 12035/51. Class 102 (i). In a variable delivery liquid fuel pump of the kind comprising a single reciprocatory plunger which has combined with it a slidable sleeve for controlling a spill port in the plunger and which is rotatable about its longitudinal axis for effecting communication of a delivery port in the plunger with each in turn of a plurality of outlet passages, the plunger is stepped and its smaller part extends through the closed end of the pumping chamber, the sleeve of which controls the spill port, being mounted on the outer end of the smaller part of the plunger. A plunger comprises a main part h, Fig. 1, its end working in a pumping chamber e, and a smaller part i extending into a fuel entrance chamber b. An axial bore j in the plunger connects a spill port o and groove p, and an outlet port t and groove u, with an inlet port m. The plunger is reciprocated by a multi-lobe cam 4 and is rotated by gear-wheels 5. A spill port sleeve q is adjustable by a manually or automatically operable lever r. In the modification of Fig. 2 the spillage control sleeve q is in the form of a piston sliding in a cylinder 8, the lower end of which constitutes the fuel entrance chamber b, and the two ends of which are connected by a throttled port 12 and passage 11. An annular groove 15 in the bore of the sleeve communicates by a passage 16 with the upper end of the cylinder 8, permitting spillage from p during each working stroke. The rate of outflow to the lower end of the cylinder depends on the adjustment of the throttle 13 at any given rate of working. At a higher rate of working liquid pressure builds up in the upper part of the cylinder and moves the piston q downwardly against the action of a spring 9, this movement causing the grooves p and 15 to come into conjunction at an earlier part of the working stroke of the plunger, thus reducing the fuel discharged to the engine along the passages k and thus automatically controlling the supply of fuel to the engine in response to the speed.
